On a Dutch forum I found out that this fly must be some Bibio species. Can it be identified from these mediocre photo's?

Thanks,
Cor

portrait of the same fly

and finally a lateral view

I found it very similar to this one! Perhaps it is a female of Bibio hortulanus. Not sure.


And in Serra da Estrela I found huge Bibio marci flies!

I think this is Bibio Anglicus.

- orange body (female)
- dark (braun) pterostigma and the wing(veins) in the back of the wing are not milkwhite.

From what I understand(from waarneming.nl) the place where you saw these bibio was Amstelveen (place near Amsterdam). Thats very special I think..

Hi Cor,

Do you have any picture with clear focus on a wing ?
It certainly looks like B. anglicus, which would be suprising near Amstelveen.

Question about the orange female of bibionidae.
Are there three orange bibionidae sp. female's in the Netherlands?

These are:
1) Bibio ferruginatus
2) B. hortulanus
3) B. anglicus

Are there also Doliphus sp. where the female's are orange? which can be confused with Bibionidae? Bibionidae sp. must have a big spine on the frontleg I guess..

I found 3 other flies the next day. I'm sorry not to have mentioned this before, but I found them near my garden. in Amstelveen, The Netherlands. They sit on Hawthorn and other shrubs (Cornus mas on the photographs) that border a football playfield! (That's Nature in Amstelveen, I'm afraid)

I made some new, and technically better, photographs, which I add here. I hope the view on the wings suffices, else I'll go and make some more today!

Note that the spine on the front leg is visible in two photographs, even if it is out of focus in one of them.

another picture

and yet another....

Yes, this should be anglicus.

Congratulations.
